24678	[PATCH] Possibility to specify custom MapPaintSettings for MapCSS rendering.	zkir	team	"== Problem

The UrbanEye3D plugin provides a 3D rendering of OSM data. To display the ground, it uses JOSM's `RenderingHelper` and `StyledMapRenderer` to render a 2D map image(s) with a custom MapCSS style.

The problem is, that the global JOSM preferences from OSM Data tab (e.g. ""Draw oneway arrows"", ""DrawSegment numbers"", `mappaint.shownames` ), are affecting rendering in 3D window also. 
This is not a desired behaviour, and it looks quite surprising. Style for the groundplane in 3D window was designed to look ""realistic"", and all titles and arrows were excluded from it. 
However, they reappear if the settings in question are activated.  (see screenshots).

== Proposed Solution

The proposed solution introduces a mechanism to create and use a ""neutral"" set of `MapPaintSettings` for the rendering process, ensuring it is independent of global user preferences.
The patch is composed of three main changes:

1. In `MapPaintSettings.java`:
   * A new static factory method, `createNeutralSettings()`, is introduced. This method returns a settings object specifically configured to be non-intrusive for realistic rendering. It disables settings that add symbolic cartographic elements (e.g., `showDirectionArrow=false`, `showOnewayArrow=false`, `showNamesDistance=0`), while inheriting other defaults (like colors and node sizes) from the global `INSTANCE`.

2. In `StyledMapRenderer.java`:
   * A new constructor is added that accepts a `MapPaintSettings` object.
   * The `getSettings()` method is updated to use these custom settings if they are provided. If no custom settings are passed, it falls back to the global `MapPaintSettings.INSTANCE` to maintain existing behavior.

3. In `RenderingHelper.java`:
   * The class is updated to take advantage of the new mechanism. It now instantiates `StyledMapRenderer` with the neutral settings provided by `MapPaintSettings.createNeutralSettings()`.

== Performance and memory impact
* No negative performance impact. No addtional operations or activites are added.
* Additional instance of MapPaintSettings is created, but only if RenderingHelper is used. In normal scenario there is no additional memory consumption.
